CPT® Code 11301

The CPT® Code 11301 refers to the procedure of shaving a single epidermal or dermal lesion located on the trunk, arms, or legs, specifically when the lesion has a diameter ranging from 0.6 to 1.0 cm. This procedure is typically performed on lesions that are either pedunculated, seborrheic keratoses, fibrous papules, or other similar types that possess a minimal dermal component. The shaving technique involves removing the lesion by making incisions that do not penetrate deeper than the middle dermis, thereby preserving the integrity of the subcutaneous layer beneath. Prior to the procedure, the area is thoroughly cleansed, and a local anesthetic is administered to ensure patient comfort. The actual removal of the lesion is executed using a blade, which may involve either a transverse incision or repetitive horizontal slicing in a consistent direction. After the lesion is excised, the physician inspects the surrounding tissue to confirm complete removal of the lesion. To finalize the procedure, the edges of the wound are smoothed, and any bleeding is controlled through the use of electrocautery or chemical cautery. The excised lesion is then sent to a laboratory for histologic evaluation, which is reported separately. It is important to note that different CPT® codes are designated for lesions of varying sizes: 11300 for lesions measuring 0.5 cm or less, 11301 for those measuring 0.6-1.0 cm, 11302 for lesions between 1.1-2.0 cm, and 11303 for lesions exceeding 2.0 cm in diameter.
